' This invention relates to devices used for measuring water to be addedto concrete and the like mixtures. v I

One of the objects of this invention is to prevent any wrong mixingby'providing a positive measuring mechanism.

Another object is to provide a device with visible indicating meanswhereby a proper mixing is assured.

Another object is to provide a measuring apparatus with a refillingmechanism to mainany desired mixing.

Another object is' to provide adjusting means for quickly and accuratelysetting theapparatus to measure any desired amount of liquids.

tain a certain amount of liquids ready for Another object is to providean apparatus that can be set and adjusted during the operation for anyamount of liquids desired in any mixture. 1 e Other objects will appearfrom the "following description and appended claims as well as from thewhich Fig. 1 is a fragmentary longitudinal midsectional view of ameasuring apparatus hav-v ing an adjustable partition whereby a suitableamount of liquids can be held readyfor a" required mixing according tothis invention.

Fig. 2 is an end elevation illustrating the controls for the measuringapparatus.

In mixing concrete it has been found that accompanying drawing, in

- it. is not alone of importance'to proportion the cement in relation toother ingredients, such as sand and rock, but that it is very essentialto maintain a certain relation be tween the water and the cement. sincea proportioning between the water on the one side and the cement mixture011 the other side has a great influence on the strength of concrete ashas been clearly shown by tests.

It is therefore one ofthe principal features of this invention toprovide an apparatus by which a certain amount of water can be held inreadiness to be added to acement mixture or similar composition.

As illustrated, thecylinder- 3 is divided into two compartments 4 and 5by'an adjustable piston 6. i

The water supply connection? allows a fill ing of the'compartment 4 and,through the connection 8 and thecommunicating pipe 9,

aiilling of the coinpartinentfi, byway oithe connection 10. I Theconnections 8 and 10 together with the communicating pipe 9 areotherwise principally usedfor air vents.

A valve 11 is provided on the outer termination of this air vent forchecking the passage through this outlet. 1

Any water accumulated'inthe compartment 4 may be drawn ofi through theoutletl2. {The plunger 6 is adjustable by the spindle 13. A scale 14 isprovided bywhich the position of the handwheel l5-can be set so as toindicate thereby the position of the piston 6. 1 The spindle with thehand wheel may be locked to the scale or other place so that the pistoncan be held in a certain position from which it may only be removed byany person that is authorized to change the amount of water supply inorder to prevent the common laborer on a job from tampering with thisapparatus. j

' The piston 6 can in this manner be set more or less towards the rightor left end of the" apparatus or in relation to the outlet connection12, so as to providea smaller or larger volume of water in thecompartment On opening the outlet 12 water is only drawn from thecompartment i, but the pistonmay be moved'at' any time to discharge thewater from the compartment 5 through the communicating pipe 9 into thecompart' ment 4 and'therei'rom through the outlet 12.

The inlet and outlet connections 7 and 12 are preferably operated in theorder illus-f tratedin' Fig. 2'by a lever mechanism that assures aclosing of one connection when the other is opened, as, for instance, ifthe outlet connection 12 is closed by a lever movement in the positionindicated at 165 the main control lever 17 by its operative connectionwith the lever 18 automatically opens the valve 7. In the reversedorder,if the valve 12 is opened by bringing the lever 16 over to theposition l indicatedin'dottedlines at 16;, the'iwhole lever meehanismisjmoved so as to bring the leverfi18tothefposition indicated in dottedI rod or link 24 connects the mainlever 1 7 with to swing around the pin21;. 1
